Overview

Amazon Web Services (AWS) is a subsidiary of Amazon that provides these metered pay-as-you-go services:

  • On-demand cloud computing platforms

  • APIs to individuals, companies, and governments

Deploying an AWS Terraform Blueprint is a three-step process where you’ll need to:

  1. Create a Terraform Blueprint

  2. Provision your Resource using Terraform Blueprint

  3. Deploy your Terraform Blueprint

 

Before you begin
Ensure that you have access to at least one resource pool.

Create a Terraform Blueprint

Create a Terraform-based Blueprint is a three-step process. You’ll need to:

  1. Configure a Terraform Backend State

  2. Create a Terraform Workspace

  3. Create a Terraform Blueprint

Configure a Backend State

A Terraform backend allows for abstraction and determines how a state is loaded, and operations executed. Terraform uses the local backend by default. In the HCP portal, a Terraform Backend state stores the current state of the deployment. [1]

To create a Terraform Backend State:

  1. Log in to your HCP portal account.

  2. Click Service Orchestration and navigate to Services > Infra as Code > Backend State > Click + New Backend State.

  3. Enter the following details in the New backend State dialog:

    1. Enter a Name for your Backend State.

    2. Select the Cloud Type from the drop-down list.

    3. Select your Resource Pool from the drop-down list.

    4. Enter a brief Description of your Backend State.

    5. To entitle users to your Backend State, select:

      • Only Me: if you do not want anyone to access your backend state.

      • Everyone: if you want to share your backend state with everyone.

      • Groups & Users: if you want to share the backend state with specific users or groups.

        1. Enter the first three alphabets of the username in the Users drop-down and select the username.

        2. Type the first three alphabets of the Group Name in the Groups drop-down and select the group name.

  4. Click Save Changes.

 

Note

  • [1] If the backend state has no state saved previously, the Terraform plan will provide you an information object which will be created.

    • Otherwise, the Terraform output will show updates and delete tasks too, which means existing resources will change if ignored.

Create your Terraform Workspace

Workspaces are collections of infrastructure that run locally. In other words, a workspace is an isolated instance of state data for a Terraform CLI. A Terraform workspace manages each collection of infrastructure with a persistent working directory, which contains a configuration, state data, and variables. You can create multiple workspaces to manage various sets of discrete infrastructure from a single configuration in a single directory. The Terraform cloud manages infrastructure collections through workspaces instead of directories. The terraform workspace organizes your infrastructure into groups. You can create a workspace to manage your collection of infrastructure resources.

To create a Terraform Workspace: [1]

  1. Login to your HCP account.

  2. Click Service Orchestration and navigate to Infra as Code > Workspace > Click + New Workspace.

  3. Enter the following details in the New Workspace dialog:

    1. Enter your workspace Name.

    2. Enter a brief description of your Workspace.

    3. Select your workspace Environment.

    4. Select the Cloud Type from the drop-down list.

    5. Select your Resource Pool from the drop-down list.

    6. Select your Backend State from the drop-down list.

    7. To entitle users to your new Workspace, select: 

      • Only Me: if you do not want anyone to access your Workspace.

      • Everyone: if you want to share your Workspace with everyone.

      • Groups & Users: if you want to share the Workspace with specific users or groups.

        1. Enter the first three alphabets of the username in the Users drop-down and select the username.

        2. Type the first three alphabets of the Group Name in the Groups drop-down and select the group name.

  4. Click New Workspace.

 

Notes

  • [1] Resource pool contains cloud provider information. Therefore, a Terraform deployment does not affect the quota limit of the resource pool.

Create a Terraform Blueprint

Terraform-based blueprints let you create infrastructure on your cloud environment using a template.

 

Before you begin
If you want to upload a Terraform-based template, follow these steps:

  1. Download the Sample Terraform Template.

  2. Zip the downloaded files.
    Example: aws-s3-bucket-tf.zip

  3. Follow Step 2c below to upload your Terraform template to the HCP portal.

Follow these steps to create a Terraform-based blueprint:

  1. Log in to your HCP portal account.

  2. Click Service Orchestration and navigate to AppStore > Click New > Select Terraform from the drop-down list.

  3. Enter these details in the New Terraform dialog:

    1. Enter a Name for your Terraform Template,
      Example: AWS S3 Bucket.

    2. Enter a brief description of your Terraform Template. This is an optional field.

    3. You can create a Terraform template using a template file in .zip format. Click Choose File to upload a Terraform template file.

    4. Configure your Terraform template version. This is an optional step.

    5. Select AWS from the Cloud Type drop-down list.

    6. To entitle users to your Terraform template, select:

      • Only Me: if you do not want anyone to access your Terraform template.

      • Everyone: if you want to share your Terraform template with everyone.

      • Groups & Users: if you want to share your Terraform template with specific users or groups.

        1. Enter the first three alphabets of the username in the Users drop-down and select the username.

        2. Type the first three alphabets of the Group Name in the Groups drop-down and select the group name.

      • If you are a Cloud Administrator, you can choose All Tenants to make the template available to all the tenants.

  4. Click Create.
